(My Notes ---I do not understand why is was reported that they have been married for 10 years ..when the marriage record was from Dec 1895...I do not understand why is was reported that Katie is the mother of 3 kids with 1 kid still livingWho are the 2 kids listed in the 1900 Census - Agens7 and Kate5 ??And if they were married in Dec 1895 - Is Kate the bio mother to these 2 girls born in 1893 and 1894 ??Or did John have a first wife ??---
